PLUMBERS FERRU LE.

SPECIFICATION forming part of Letters Patent No. 494,413, dated March28, 1893.

Application filed November 11, 1892. Serial No. 451,596- (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. COTTER, a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented certainlnew and useful Improvements inPlumbers Ferrules; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to produce a novel article of the classknown as plumbers ferrules, i. e. a ferrule used by plumbers in making'aconnection between a lead pipe and an iron pipe, it being of courseunderstood that it is impossible to form either a wiped or a packedjoint between lead pipe and iron pipe without the interposition of'a'ferrule'made of some metal to which solder will adhere in making a wipedjoint and which will not be affected by the pouring of molten lead inmaking a packed joint. Various styles of ferrules have been usedheretofore for this purpose, the ferrule most commonly used howeverbeing one made of cast brass.

My novel ferrule is especially adapted to take the place of cast brassferrules, it being very much stronger, much lighter, non-porous, andvery much cheaper to produce.

In the accompanying drawing forming part of this specification thefigure is a sectional view illustrating the manner in which a section oflead pipe is joined to a section of iron pipe by the use of my novelferrule.

A denotes a section of lead pipe, B a section of iron pipe which isprovided with the usual socketl at its end, said socket terminating in ashoulder 2, and C represents my novel. ferrule which is a drawn,seamless, brass or copper tube having at its lower enda flange 3 whichrests upon shoulder 2 in the socket in the iron pipe. In joining a leadpipe to an iron pipe it is necessary that two perfect joints be made,forthe reason that it is impossible to pour molten lead against a lead pipewithout melting it.

The ferrule is in practice connected to the iron pipe by what is termeda packed joint.

The ferrule is placed in thesocket, the flange 9. The end of the pieceof lead pipe is simply placed within the offset, resting upon shoulder9, and a wiped joint formed in the usual manner covering the 'point 'ofjoinder of the lead pipe to the ferrule. For convenience in making thewiped joints, that is, so that they will alwaysbe ready forimmediateuse, the upper ends of the ferrules are tinned as at 10, the lower edgeof the tinned portion being indicated in the drawing bya line and thetinned portion above the line being indicated by lighter shading.

Ferrules made in this manner are very much lighter than any other styleof ferrule known to the trade, making them much more convenient to shipand to handle, they are very much stronger for the reason that alltubing of the class from which these ferrules are made is tested to 500pounds pressure before being shipped, and another and veryirnportantadvantage is that there is no loss from breakage in dropping, cast metalferrules being very apt to crack if dropped.

Having thus described my invention, I claim v In combination, with theiron pipe 13, the flanged ferrule secured thereto by a packed joint, anoffset 8, formed at the opposite end of the ferrule, a lead pipe fittingwithin the same, and a wiped joint securing the ferrule thereto,substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES A. COTTER.
